Method for supplying an internal combustion engine with conditioned combustion gas, device for carrying out said method, method for determining the quantities of pullutants in the exhaust gases of an internal combustion engine, and device for carrying out said method

A method for determining the quantities of pollutants in the exhaust gases of an internal combustion engine, including the determination of the pollutant concentration and the quantity of the flowing exhaust gas whereby diluting of the exhaust gas takes place by using a diluent gas of known composition, characterized in that an essentially constant and fully conditioned quantity of humidity and/or temperature-conditioned combustion gas is supplied to the internal combustion engine at each instant whose quantity corresponds to at least the maximum quantity required by the respective combustion engine, and whereby the exhaust gas is diluted with the quantity of combustion gas that is not used by the internal combustion engine.

24-41. (canceled)

A device to determine the quantities of pollutants in the exhaust gas of an internal combustion engine comprising at least one measuring point, for example a sensor or sampling device, for determination of the pollutant concentration, and a determination device for the flow of gas whereby said determination device is provided with a passage leading from the exhaust gas passage to supply passage for a diluent gas of known composition, characterized in that the supply passage for the diluent gas is designed for at least the maximum quantity of combustion gas required by the respective internal combustion engine and whereby an intake line, which can be connected to the internal combustion engine, branches off from said supply passage.
